Beschreibung
Zusammenfassung:	The inventive method relates to a reinforcing treatment of welded metalwork joints using a power ultrasound. The method can be used for mechanical engineering, shipbuilding, bridge engineering and other branches of industry and construction producing welded structures which can be safely used at conditions of static, dynamic and repeated-variable loading. The inventive method involves the step of calculating normalized residual compressive stresses to be produced during the ultrasound impact processing. The stresses are related to the geometrical dimensions of a groove formed when the area disposed along a line between the joint and a base metal is treated. The invention makes it possible to maximally increase the fatigue limit and the cyclic life duration of welded joints.
